LONG-TIME BURNER.

specification of Letters Patent.

Patented July 6, 1%1? TO (M whom it may concern Be it known that I,Fnnnnniok Dunssnn, a citizen of the United States, residing at the cityof New York, borough of Manhattan, in the county and State of New York,have invented certain new and useful Improvements in Long-Time Burners,of which the following is a full, clear, and ex act specification.

My invention relates to improvements in lamp burners, and the same hasfor its ob ject to provide a simple, eflicient and reliable long timeburner for use in signal and other lamps.

Further said invention has for its object to provide a long time burnerby means of which the consumption of oil will be materially reducedwithout impairing the brilliancy of the flame.

Further said invention has for its object to reduce the size of theflame, and still obtain a pure white light.

Further said invention has for its object to provide a burner in whichthe means for conducting air to the flame necessary to sup portcombustion is so brought into contact therewith as to produce a small,attenuated flame of great brilliancy and whiteness.

To the attainment of the aforesaid objects and ends my inventionconsists in the novel details of construction, and in the combination,connection and arrangement ot' parts hereinafter more fully describedand then pointed out in the claims.

ln the accompanying drawings forming part of this specification, whereinlike numorals of reference indicate like parts, Fig

ure 1 is a top view showing one form of' burner constructed accordingto, and embodying my said invention; Fig. 2, isa central verticalsection taken on the line 2-2 of Fig. 1.; Fig. 3, is a detail sectiononthe line 3 3 of Fig. 2, showing the upper end of the wick tube, andassociated parts, and Figs. 4 and 5 are detail perspective views, partlybroken away, showing the deflecting hood, and flame shield,respectively.

In said drawings designates the base portion of the burner having areduced end 11 provided with screw-threads tor application to the oilfont, and a convexed top 12 having an annular shoulder or head. alongits edge.

14 denotes the wick tube which is centrally arranged in the base portion10,. and

has its lower end secured to the bottom of said base portion, and itsupper end projecting above the convex top 12. Upon the base portion. 10,and engaging the annular shoulder or bead 13 is disposed a ring 15 whichis provided with four equally spaced uprights 16, 16, between which theair for supporting combustion is admitted to the burner.

17 denotes a chimney gallery which is supported upon the upper ends ofthe uprights 16, 16. By preference the uprights 16, 16 and the chimneygallery 17 are made integral. The chimney gallery 17 is provided alongits edge with outwardly extending ears 18, 18 which are provided withopenings 19, 19, through which extend upwardly the free ends of springfingers 20, 20. The said spring fingers 20, 20 are provided at theirlower ends with inwardly and upwardly extending portions, and saidinwardly and upwardly extending portions are secured to the uprights 16,16 by lugs, not seen, struck up from said uprights. The upper free endsof said spring fingers 20, 20 are bent sharply outward in order toengage the lower end of a chimney, and hold the same in position uponsaid gallery.

22 denotes a cone which is provided at its lower edge with supports 23,23 which extend outwardly a short distance to the inner sides of theuprights 16, 16, and then downwardly to the upper surface of the top 12,and have their vertical portions secured to, and against the inner sidesof the uprights 16, 16. The said cone has its upper end slightlyflattened upon four sides in order to produce a substantially squareopening at the upper end thereof, and at two of its opposite edges saidcone is provided with inclined deflecting. blades 24-, 24; which extendupwardly and inwardly, and have their parallel edges slightly rounded.The cone 22 is so positioned about the wick tube 1 1' that its upperedge shall be slightly above the top of said wick tube.

Within the cone 22, and surrounding the upper end of the wick tube 14 isdisposed a guard. shield 25 consisting of a V-shaped plate having aci-cular opening 26 in its base of appreeiab y greater diameter than theexterior diameter of said wick nbe, to form an annular air space betweenthe edge of said opening and the outer side of said wick tube. The widthof said guard shield is substantially equal to the distance along I theupper edge of the cone between the deflecting blades 24:, 24, and thusprovides openings intermediate the inner sides of said cone, and theinclined edges of said guard shield. From the horizontal upper edges ofthe guard shield 25 extend downwardly and outwardly tongues 27 27 whoseinclination and length correspond with that of the cone 22.

28, 28 denote ears which extend from the loweredge of the cone, midwaybetween the supports 23, 23. The said ears are bent in wardly andupwardly to embrace firmly the lower ends of the tongues 27, 27 of theguard. shield 25 in order to hold said guard shield dul-y in position.with said cone and surrounding said wick tube.

29 denotes a wick-raising shaft which is suitably mounted in the baseportion 10, and provided at its inner end with a spur wheel 30 extendingthrough an opening in the wick tube, and at its outer end said shaft 29is provided with an operating wheel 31.

The operation of the burner is largely obvious, but it may be noted thatin operation the main supply of air necessary to support combustion isconducted to the flame between the inner wall of the cone 22, and theinclined edges of the guard shield 25. The flattening of the flame isprevented largely by the supplying of air through the annular spaceintermediate the base of the V-shaped guard shield 25 and the outer sideof the wick tube 14 which serves to conduct a thin tubular sheet of airto the flame, and at the same time act to confine the same in order toform a small cylindrical flame of great whiteness. The operation of theflame is further controlled by the action of the deflecting blades 24,24c.

It will thus be noted that by means of my invention I am enabled toprovide a burner yielding a reduced flame, of great whiteness, andconsuming a minimum of oil.

Having thus described my said invention, what I claim and desire tosecure byLetters Patent is'- 1. A lamp burner comprising a wick tube, asupport therefor, a cone mounted upon said support and surrounding saidwick tube, and a guard shield secured at its ends to said cone, andprovided at its base with .an opening through which the upper end ofsaid wick tube extends; said opening being appreciably larger indiameter than said wick tube to provide an annular air space between theedge of said opening and said wick tube, substantially as specified.

2. A lamp burner comprising a wick tube, a support therefor, a conemounted upon said support and surrounding said wick tube, said conehaving a squared upper end, deflecting blades extending upwardly andinwardly from opposite sides of said cone, and a V-shaped guard shieldhaving its opposite end secured to the edge of said cone intermediatesaid deflecting blades, and provided at the junction of its inclinedmemhere with an opening surrounding the upper end of said wick tube;said opening being of such diameter relative to said wick as to form anannular air space intermediate the edge of said opening, and the outerside of said wick tube, substantially as specified.

3. A lamp burner comprising a wick tube, a support therefor, a conemounted upon said support and surrounding the upper end of said wicktube, oppositely-arranged, defleeting blades provided upon oppositesides of said cone and extending upwardly and inwardly therefrom, anupwardlyflaring guard shield having an opening therein. to receive theupper end of said wick tube to provide an annular air space between theedge of said opening and said wick tube, and oppositely arrangedsupporting members thereon, oppositely disposed ears extending from thelower edge of said cone and engaging said supporting members whereby tomaintain said guard shield in position within said cone, substantiallyas specified.

4. A lamp burner comprising a wick tube, a support therefor, a conemounted upon said support and surrounding the upper end of said wicktube, said cone having a squared, open upper end, deflecting bladesarranged upon two opposite sides of said cone and extending upwardly andinwardly, a V-shaped guard shield having an opening therein andsurrounding the upper end of said wick tube to provide an annular airspace between the edge of said opening and said wick tube, andoppositely arranged supporting members on said guard shield engaging theinner wall of said cone intermediate said deflecting blades, andoppositely arranged ears extending from the lower edge of said cone, andengaging the lower ends of said guard shield supporting members, wherebyto support said guard shield in position within said cone, substantiallyas specified.
